空间目标姿态角测量计算方法研究

Research on computational method for extended target posture angle

新型武器在靶场试验鉴定时,除了测量其空间X、Y、Z坐标外,还新增加测量其空间偏航角、俯仰角等姿态信息,这也对靶场试验数据处理提出了新要求。本文以靶场普遍使用的经纬仪为测量设备,提出了一种新的算法。该计算方法通过平面坐标系与三维坐标系转换、观察坐标系与世界坐标系转换,利用三维透视投影变换理论,推导出相应计算公式,并给出了单站计算目标姿态角的精度分析。该方法可以普遍应用于光学成像测量设备和电子成像测量设备的姿态角数据处理中,具有一定的独创性和先进性。

When the new weapons are tested on the shooting range, besides the interspace coordinate X,Y,Z, measuring the interspace leeway angle, the pitching angle, and etc pose information are added , which put forward the new request on shooting range test data dealing. This article bring forward a kind of calculate method with the wide using theodoliteas the main testing equipment. Calculate aim posture angle is the demand of development for data processing,the computational method utilizes three-dimension to perspect the projection and vary the theory, derive out the corresponding calculation formula. This method can apply optics formation of image measure equipment and electronic formation of image measure posture corner of equipment of the data processing generally, which has certain originality and advance
